Newcastle defender Jamaal Lascelles is attracting interest from Turkish side Besiktas after falling down the pecking order under Eddie Howe.
Lascelles is the club's captain but is no longer guranteed a first team starting spot this season - with Fabian Schar and Sven Botman often selected ahead of him as the first choice centre-back pairing.
The centre-back has started 12 out of 20 games in the Premier League this season, while Schar has started every game under Howe.
Botman, meanwhile, is back in the squad after recovering from a knee injury that kept him out for three months.
